1 Claim.

This invention relates to electrically charged wire fences and to the posts and insulators therefor. a

An object of the invention is to produce posts which can be readily installed in association with an insulator of novel construction, and also novel means for anchoring the insulator to the post, whereby the said insulator may be expeditiously secured in place or released.

A further object of the invention is to provide insulators which are held or by which barbed wire or smooth wire may be anchored and held in place with relation to the post, the said insulator being provided with means for expeditiously inserting the wire in the insulator and in which ing part of this application, wherein like charac-.

ters denote corresponding parts in the severa views, and in which:

Figure 1 illustrates a view in elevation of a fence post with attached insulators embodying the invention;

Figure 2 illustrates a view at that shown inFig. 1;

Figure 3 illustrates an enlarged detail view of a fragment of a post with the insulator attached;

Figure 4 illustrates an enlarged detail view of the other side of the assembly shown in Fig. 3;

Figure 5 illustrates a view in elevation of the assembly at right angles to the position in which it is shown in Fig. 4;

Figure 6 illustrates a top plan view;

Figure 7 illustrates a sectional view of the assembly on the line 1-1 of Fig. 3;

Figure 8 illustrates a sectional view on the line 8-8 of Fig. 3;

Figure 9 illustrates a view of the insulator having depending lateral channels for the wire;

Figure 10 illustrates a view in elevation at right angles to the position of Fig. 9; v

Figure 11 illustrates a sectional view of the form illustrated in Fig. 9 with a plain wire installed;

right angles to Figure 12 illustrates a plan view of that form shown in Fig. 9; and v Figure 13 illustrates a sectional view of the assembly of the wire and insulator on the lin I3--l3 of Fig. 11.

In this drawing a fence with two wires l5 and I6 is shown, although for charged wire fences one wire may be sufficient, but a number of wires may be used to suit particular requirements. The post, in the present embodiment of the invention comprises a base I! of angle iron, to the upstanding flange l8 of which a post l9 and braces 20 are secured; it being shown that the ends of the braces remote from theflange are attached to the post by fastenings 2|, such as rivets or the like. It is shown that the post is angular in cross section and that insulators 22 have an angular corner, as at 23, which fits against the inner surface of the angular post. The lower part of the insulator, aside from being angular at one corner, is preferably convex or circular, as at 24. The insulator is anchored to the post by a clip 25 that embraces the lower portion of the insulator. One end of the clip is straight and contacts the outer surface of one of the flanges of the post and extends therebeyond and is provided with an aperture 26, whereas the opposite end of the the extended portion of the first described end of the clip, and the said extension has an aperture 26 for the reception of a clamping bolt 21 and a nut 28 threaded on the bolt will operate to draw the ends of the clip together and to bind the clip into frictional contact with the insulator so that the said insulator will be effectively anchored to the post.

The insulator in the form illustrated in Figs. 3 to 8 has a slot 29 extending inwardly from its upper end merging or intersecting horizontally disposed slots 30 and 3t on each side of the inwardly disposed slot. Hence, wire may be inserted in the slot 29 from the top and when the intersecting slots are reached, the wire may be turned to a position at right angles to that in which it is inserted in the slot 29 and the said wire will thereby be held against accidental dis-,

and 34 which extend downwardly and outwardly to the side surfaces of the insulator and when a wire 35 is applied to an insulator of this character, it will have the appearance in which it is illustrated in Figures 11 and 13.

In practice it has been found more desirable to employ the insulator shown in Figure 1 in connection with barbed wire conductors, whereas the form of insulator of Figure 3 is used to better advantage with plain fence wire.

I claim:

In a wire fence, a post angular in cross section, an insulator having at its lower portion an angular corner, the faces of the angularly disposed portions fitting against the inner surfaces of the angularly disposed portions of the post, the said insulator having a convex surface between the angular surfaces, a clip embracing the convex portions of the insulator and having one end extending across the outer face of one of the flanges of the post and projecting beyond the said post, the said projecting portion having an aperture, the said clip at the opposite end engaging the outer surface of the other flange of the post and having an extension parallel with the extended portion of the first mentioned end, the said projecting portion having an aperture alining with the first mentioned aperture, and a clamping bolt extending through the apertures for binding the clamp against the insulator and the said flanges
